30 years after the Chinese army crushed demonstrations centered on Tiananmen Square, "Tank Man" — the person who boldly confronted a convoy of tanks barreling down a Beijing avenue — is as much a mystery as ever. The enduring figure of Tank Man was photographed on June 5, 1989, in the immediate aftermath of a deadly government campaign to clear Tiananmen Square of protesters. The Chinese government has worked to eliminate the memory of Tank Man, censoring images of him online and punishing those who have evoked him. Outside of China, Tank Man has endured in popular culture, the subject of numerous books, documentaries, television shows and art exhibits.
